And he spoke a parable unto them,
Can the blind lead the blind? shall they not both fall into the ditch?
All Commentaries on Luke 6:39 Go To Luke 6

AD 444

That is to say, first show yourself clean from great sins, and then afterwards shall you give counsel to your neighbor, who is guilty only of slight sins.
